Determine the density of nh3 gas at 435k and 1.00atm

We assume that this gas is ideal. Therefore, we can use the ideal gas equation which is expressed as:

PV=nRT

We manipulate this equation to give us an expression which will correspond to density. We do as follows:

PV = nRT

P/RT = n/V where n = m/MM

P (MM) / RT = m/V = density

Density = 1.00 (17.03) / 0.08206 (435)

Density = 0.48 g / L
